• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang x)) hoi. lieu va chat doc ((ca danh) OR (ca dan)) cau cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) OR (nang x)) hoi. lieu va chat doc ((ca danh) or (ca dan)) cau cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) OR (nang x)) hoi. lieu va chat doc ((ca danh) or (ca dan)) cau cua triet*.
